This may be a dumb idea
I have an internal (192.168.0..) network and an external on a 128k ISDN
Firewalled with ipchains on RH7. I have just been connected with an ADSL
line. I would like this to be used for outgoing port 80 browsing etc only
and use the 128k ISDN for incoming port forwards
Search for a copy of source-address-routing howto or mini-howto.. you'll
need to use iproute2 for the stuff you want to do.
At home I have 2 ppp links, and the machines behind NAT, use the cheaper
unlimited ppp link, while my subnet based machines use the perm expensive
modem :P
Good luck :P

of the time. But some times it really does end in tears.
